RIVETING-IVIACHIN.

SPECIFICATION forming part of Letters Patent No. 609,479, dated August23, 1898.

Application tiled October 7,1896. `Serial No. 608,150. (No model.)

To all whom. it may concern,.-

Be it known that I, JOSEPH W. THOMPSON,

Aof Salem, in the county of Columbiana and State of Ohio, have inventeda certain new and useful Improvement in Riveting-Machines, of whichimprovement the following is a speciiication.

The object of my invention is to provide an appliance for eyeleting orriveting together sheets or strips of leather, pasteboard, or othercomparatively soft material or fabric which shall be of simple andinexpensive construction and in the operation of which the rivet shallbe effectively protected against displacement.

The improvement claimed is hereinafter fully set forth.

In the accompanyingdrawings, Figure lis a side view, partly in section,of a rivetingmachine embodying my invention, the movable parts beingshown in the positions occupied when in readiness for operation; Fig. 2,a similar view with the parts in the positions occupied at theconclusion of the operation; Fig. 3, a horizontal section at the line ofFig. l; and Figs. t and 5, vertical central sections, on an enlargedscale, through the lower right-hand portion of the machine,

l showing the parts in positions corresponding with Figs. 1 and 2,respectively.

In the practice of my invention I provide a frame or body A1, which maybe connected to any suitable base or support 2 and which is recessed orcut away on the side nearest the operative mechanism for the receptionof the material a to beriveted and of members of said operativemechanism. An operating-lever 3, which is bifurcated at and adjacent toits inner end to clear a movable plunger 5, is pivoted to the upperportion of the frame 1 bya pin 4. The plunger 5 is iitted to reciprocatevertically in a boss or annular guide 6 on the frame and is externallythreaded at and adjacent to its lower 4end (which is properly formed tosplit and turn over a rivet) to `engage a cylindrical hub or boss 7 onthe end of the upper arm of a` U -shaped carrier 8, having acorresponding hub or boss 9 on the end of its lower arm in line axiallywith the boss 7. The operating-lever 3 is coupled to the carrier 8 bylinks 10, fitting pins 11, projecting laterally from theoperating-lever, and pins 12, similarly projecting fromv the hub 7 ofthe upper arm of the carrier 8.

An anvil 13 is securedto the bottom of the frame 1 in line axially withthe line of traverse of the plunger 3, and the lower boss 9 of thecarrier 8 is bored out to tit truly around the anvil 13. Vhen inposition for operation, as shown in Figs. 1 and 4., the carrier, throughthe cylindrical passage 14. of its boss 9, forms a receptacle and guardfor the rivet b, the

' head of which is set upon the top of the anvil 13, and the rivet isprotected from displacement in theoperation of the machine by saidreceptacle, which does not pass clear of its head until after it haspenetrated the material to be riveted.

The threaded connection of the plunger and carrier enables the plungerto be adjusted'to suit different thicknesses of material, as desired,and after adjustment the carrier and plunger form a rigid structure,which is accurately guided in its upward and downward movements by thebearing of the plunger in the boss 6 of theframe and the sliding tit ofthelower boss 9 of the carrier on the anvil. The recess or space betweenthe arms of the carrier admits of the requisite projection of thematerial'on the inside of the axial line of the plunger and anvil.

In operation the rivet l) is placed with its `head on the top of theanvil 13, and the piece I claim as my invention and desire to secure 1.In a riveting-machine, the combination, substantially as set forth, ofan anvil, a plunger which is movable in line therewith, and arivet-guard connected to and movable with the plunger, and guided on theanvil.
